Best ResponseYou've already chosen the best response.1If the major axis is 26, then 2a is 26 and a is 13. If the minor axis is 24, then 2b is 24 and b is 12. Use the values of a and b to calculate c

Best ResponseYou've already chosen the best response.0The length of the major axis is 2a and that of the minor axis is 2b like @begzat said. Find the eccentricity of the ellipse sing \[e ^{2}= 1  b ^{2}/a ^{2}\] [when a>b] .. the distance between the focii is 2ae
